Bad Defaults Interaction

[jpulec]

It seems that minimist is providing default values for some options that are not always the same as what the defaults are for prettier. This becomes an issue when trying to using a prettier config file that only specifies some options, but expects to fall back to prettier's defaults for others. This is because currently, when using the file-override config preference, the default values from minimist are being overridden by the resolved prettier config, but resolveConfig only returns what it finds in a config file, and does not have keys for any default options.
